A true audiophile design, the twenty® sub is at home playing music or movies whilst delivering precise, dynamic results, no matter what the volume level.

The slender cabinet blends beautifully with any interior. Housed within is a long and highly effective ATL, which, when teamed with the twin 6.5-inch custom bass units, goes down to a staggering 22Hz.

The high-mass, resonance-absorbing plinth eliminates unwanted vibration, offers cable management, and provides an ideal stable platform.Active electronics derived from our renowned professional designs offer on-board DSP that optimises the driver responses and provides an array of low-pass filtering, frequency adjustments and a parametric EQ for perfect in-room tuning. Power is supplied by PMC’s 400W Class-D ultra-low-distortion audiophile amplifier, which allows for both balanced analogue and digital connections.

Thanks to its versatile inputs and filtered and unfiltered outputs, whether it’s used in a supreme multichannel AV system or as the perfect sub-bass addition to a passive 2.1 music system, the twenty® sub is a truly future-proofed package.

Customer Reviews

"It is perfect ! It sounds great. I'm a sound engineer working with big brands for P.A's. There would have a lot of things to say. But the PMC are so much more realistic! Regards"
Mr P, Gembloux
"Very early days and I'm confident I've haven't even scratched the surface of what this sub can do. I'm sure I've got a long way to go to get the best out of it but so far its very very good. No problem integrating it with my mains for music and its more than capable with film. This is one serious sub, it's a sizeable piece kit capable of shifting a lot of air if thats your thing, I prefer to only notice its absence which its equally good at. It nicely complements the other twenty/twenty5 speakers! A very nice addition for your pmc addiction!"
Mr J, St. Neots
